RAILWAY-RAIL ANCHOR.

Application filed January 31,1928. Serial No. 250mm.

This invention pertains to an improved one piece rail anchor or anticreeper especially designed to be secured to the baseportion of railway track rails and inengagement with stationary parts of the road bed for the purpose of preventing longitudinal displacement of the rails during the travel of the rolling stock thereover.

The main object of the invention is to provide a simple, strong, durable, and economical rail anchor, or anticreepeij which when applied will effectively resist the creeping tendency ofthe rail. r

Another object of the invention is to so construct my improved anchor that any tendency oi the railto creep will oscillate the anchor-about its fulcrum against the tie and cause the aiichorto more vintensely grip the rail. I r :1 I

A further object of the invention is to provide a rail anchor formed of a single piece of sheet metal, suchas heat treated steel, which will, under all conditions rigidly lock a rail against creeping toward an adjacent tie.

The foregoing and such other ob ects as may appear from the ensuing description are attained by the construction, arrangement,

location and combination of the several parts hereinafter morefully described, illustrated in the accompanying drawings, and particu larly pointed out in the claims appended'hereto, it being understood that slight changes in the precise form, proportions and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

, In the accompanying drawings forming a part of thisspecificationit will be seenthat Figure l'is a side elevation of the improved device embodying my invention applied to a track rail, showing the track rail in cross-section and in side elevation a railway tie broken away. I

Figure 8 is aside elevation of a slightly modified form of anchor showing the said anchor detached from the track rail, and

'' Figure .9 is an end elevation of the same,

looking from the right hand end of Fig. 8.

In the embodiment of my invention as illus-. trated it will be seen that the numeral 1 designates arailway track rail and 2 an underlying cross-tie forming a stationary part of the, road bed and supporting the rail 1, thesaid rail havinga tendency to creep, when subjected to the strain caused by the travel of the heavy rolling stock thereover.

a My improved railanchor may be-formed in any suitable or desirable manner, but is preferably formed from a single piece of (hot pressed.) high grade sheet steel of the desired I or required length, the solid depending body portion 3 of whi'ch is formediwith an inwardly concavoi-convexportion 4 and an outward- 1y concavo-convex portion'5, forming a substantiallyS-shaped depending portion, said concavo-convex portions adding materially to the strength ofthe anchor, the outer rounded surface of the portion 5 normally resting in contact with the tie throughout the entire lengthof the anchor, when said anchor has been applied to the' track rail, as is clearly shown in Fig; 2 of the drawings. The roun ed surface of the portion 5, which rests in contact with the tie, thus prevents the tie, from being out, chipped or otherwise damaged by theforcible-engagement therewith of the anticreepingdevice. V i

It will be observed that one end of the upright portionfi of the anchor is provided with a" jaw member 7, said jaw member being formed, with a laterally extended rightangle upwardly inclined flangerS at its top, and a;

lower laterally extended upwardly inclined portion 9. below, 'whichlatter portion nor mally rests in contact with the inclined upper surface of the base of the track rail at one side thereof and at the base of the jaw member is formed av laterally extended flange 10'v which is adapted to have a clamping contact with the lower'face of the rail base, while the opposite end of the anchor is provided with an upright portion 11 which is adapted to snap up,

slightly overlap and clamp the other side or the rail base when the anchor is securely fastened to the rail, and the end portion 11 is provided with a laterally extended flange 12 adapted to have close contact with the edge of the rail base, said flanged portions serving to materially strengthen the form ation of the device.

By reference to the slightly modified form of anchor shown in Figs. 8 and 9, it will be,

seen that the body portion 13 and the jaw end portion 14- are formed substantially as hereinbGfOIG described, while the end portion 15 is formed with an outwardly extended flange 16, all oi? the flanged portions serving to strengthen its formation and to greatly in crease its bending resistance.

It will be seen that the lower flanged portion 9 forming a portion of the jaw member 7 extends outwardly and is adapted to contact with the upper inclined surface of the rail base, and since these anchors are attached to the rail base by driving the same at its heaviest end until its opposite end snaps into contact with the upper face of the rail base, it will be obvious that as thejaw 7 is forced into its proper position the portion 9 is caused to produce an intense gripping power in contact with the rail.

It will be readily perceived that by the construction of anchor hereinbetore described that any tendency ofthe rail to creep imparts a corresponding tendency to rock the anchor about its fulcrum against the tie. S .ch tendency of the anchor to rock causes the flanged portions 9 and 10 of the jaw member to more intensely grip the upper and lower surfaces, respectively, of the rail base. Any tendency, therefore of the rail to creep results in the anchor being more tightly clamped to rail base, and hence more -forcibly resists any creeping action thereof.

It will be readily evident that this particular formation of anchor including the plurality of flanges and the body formation are all contributing factors in greatly strengthening the anchor, thus preventing breakage, bending, springing or dislodginent of the anchor when properly applied in position. I

It will be seen that the contour of the lower or body portion of the anchor is of such iparticular shape that it avoids contact at depth with the road ballast, thus avoiding friction and weakening of the anchor by pounding upon the ballast during the passage of the rolling stock thereover.

Having thus described my inventionwhat 1 claim and desire to secure by Letters Patent is 1 1. A single piece rail anchor comprising a sheet of steel formed with a double concavo convex body portion, a jaw member formed at one end having a top flanged portion and a low r flanged portion, and a clamping por tion a its other end.

A 'n le piece rail anchor comprising a sheet ol .5 mg steel formed with an upright and double concave-convex d pending body portion, a jaw portion at one end formed with a plurality of outwardly extended flanged portions and a clamping portion at its other end.

A single piece rail anchor comprising a sheet Oi high grade steel iormed with anupright and a double concavo-convex depending body portion, a jaw member having a plurality o't laterally extended flanges above the rai base, and a laterally extended flange below the rail base, and a clamping" portion at its other end.

n si gle piece rail anchor comprising a sheet of steel termed with a depending bot y portion, said body portion being formed with anupright portion anda substantially i s-shaped portion, a jaw member at one end provided with a plurality of laterally extended flanges, and a laterally extended flange, and a clamping portion at its other end.

5 sh et of steel formed with a bodyportion,

said body portion having an uprightportion and a substantially S-shaped portion, a jaw 01 steel termed with a downwardly extended body portion having a double con cavoconvex portion, a jaw member at one end termed with a plurality of extended flanges at one side thereof, and a clamping portion at its other end.
